Antenna package and image display device including the same

Abstract

An antenna package according to an exemplary embodiment of the present invention includes a first antenna device which includes a first antenna unit including a first radiator, a second antenna device which includes a second antenna unit including a second radiator whose polarization direction is perpendicular to the first radiator, a first circuit board electrically connected with the first antenna unit, a second circuit board electrically connected with the second antenna unit, and a third circuit board on which at least one antenna driving integrated circuit (IC) chip electrically and independently connected to the first circuit board and the second circuit board is mounted. By supplying power to two antenna devices having different polarization directions, respectively, signal interference and signal loss may be prevented, and dual polarization may be implemented.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY[0001]This application claims the benefit under 35 USC § 119(a) of Korean Patent Application No. 10-2020-0138106, filed on Oct. 23, 2020, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes.BACKGROUND1. Field of the Invention[0002]The present invention relates to an antenna package and an image display device including the same, and more specifically, to an antenna package including an antenna device and a relay structure, and an image display device including the same.2. Description of the Related Art[0003]Recently, according to development of the information-oriented society, wireless communication techniques such as Wi-Fi, Bluetooth, and the like are implemented, for example, in a form of smartphones by combining with image display devices. In this case, an antenna may be coupled to the image display device to perform a communication function....

AI Technical Summary

Benefits of technology

The present invention provides an antenna package and an image display device with improved radiation characteristics and signal efficiency. The first and second antenna units have polarization directions perpendicular to each other, which prevents signal interference and loss and reduces fading. The multiple antenna devices are spatially separated, allowing for selection of a resonance frequency with less signal interference or synthesizing and transmitting / receiving multiple resonance frequencies. The first and second antenna devices are electrically connected to the third circuit board through separate circuit boards, simplifying the connection process. The antenna package improves optical characteristics such as radiation characteristics and transmittance for high-frequency or ultra-high-frequency band applications.

Problems solved by technology

However, when a driving frequency of the antenna is increased, signal interference and signal loss may be increased in a high frequency or ultra-high frequency band.

For example, Korean Patent Laid-Open Publication No. 2013-0095451 discloses an antenna integrally formed with a display panel, but does not consider a structure to increase signal efficiency in a high frequency or ultra-high frequency band as described above.
